From the recording and production quality, I assume that sus49's track is probably part of a commercial release that sus49 is working towards.  Which is great, excellent, and a very worthy project for any musician.

Before some folks get the "Oh, I couldn't do that.." thought going about their own playing/music, a project does not have to be mixed/engineered/produced at that level to be worth doing.

There can be a lot of good reasons to work towards something like a CD project.  Sure the odds may be extremely small that you'll make it onto the Billboard Top 10 or other "famous" degree of notice.  But the process, from thinking about what songs you would like to put on something like a CD to deciding what you'd like for cover art, it can give some direction to what you do as an artist and make practice feel more like it is work towards.. something.

It can get you thinking about who you are as an artist/musician, what you are trying to say to the world (or at least the people that may give it a listen).  So far as I ever have seen no method book and only a few teachers out there will tell you that you need to do that.  But it is an important part of developing as an artist/player/musician.  Getting a clearer idea of your direction and what you are trying to do can help keep your inertia up and give a reason to "why should I practice today?"  Maybe even a reason to put in another 15 min or so now and then.

CDs and even single recorded tracks can also get people interested in what you are doing.  That can lead to having listeners, but also to meeting other musicians who might be interested in collaborating or who will give at least their moral support.  It can also be enough to get you into some talks with engineers, producers and other folks that you might never meet otherwise.  You just never know how far it can go.

You also may make some money at it.  I can already hear folks out there saying "and you might NOT.."  LOL  I will agree that is true, but point out that if you don't put anything out, then "NOT" is more of a sure thing.  If you put out some tracks, and especially if you also make them available as a CD or something that people can maybe listen to in their car or etc easily, then the possibilities are there.

I won't kid you, I never made a fortune on putting out CDs or tapes or etc.  But my last CD project was back in about 1999 and I did make enough to pay some bills and to buy a new computer.  More interesting to me is that even after that many years, I still sometimes get contacted about it, or (once in a blue moon) meet someone who actually heard and remembers that music.  

It isn't just CDs or commercial type releases either.  Recently I ran into someone I met at a Christmas party over 20 yrs ago.  At that party, I played a tape of some stuff I had thrown together as holiday music.  It wasn't anything fancy, a half dozen little instrumentals that were either single instrument or minimal multitrack where it was one instrument playing melody over a track of accompaniment on another instrument.  In the course of the assorted "Hey what are you up to these days" talk, they asked if one of those pieces had made it into any of my projects.  It had been over 20 yrs and they could hum enough of their favorite one that I was able to remember it.

No, it hadn't.  It had been a one shot recording with only one tape copy and the tape is long dead (probably recorded over, as well as worn out and discarded).  But finding out that someone remembered it well enough through all those years to be able to hum it back to me?  Oh, it sure as heck WILL be!  LOL  Any piece with the potential to be that memorable to anyone is definitely one that deserves to be developed, practiced, polished, recorded and put out for people to hear.

Especially considering I play some actual violin these days, and back then it was just a violin "patch" on an electronic keyboard.  I worked it out on violin and it went right into the top rotation list for my current practice pieces.  It definitely is slated for the current CD project, and the person (who I only briefly met at that party long ago) was added to my list of listeners who get to hear all the rough little bits of things as I work on them and get kept up to date on any projects I'm doing.

Back to the point though.. If there hadn't ever been a tape, if there hadn't been CDs put out, and if people hadn't gotten to hear it, some cool stuff probably just couldn't have happened. 

It is a worthwhile activity, and there can be some nice ripples from it for years.  As an artist/musician, you do not want to miss out on the possibilities.

Oh, I hear you on the "perfectionist" thing, sus49!

I have never been even near 100% pleased with any recordings I put out over the years.  But an important learning experience can be to find out that even though you feel it was far from perfect, listeners may still like it and not hear the flaws that you do.

And it is hard, doing original music, since many people (present company happily not included) will go "Oh, that sounds like" and rattle off something that your work maybe vaguely reminds them of, like they think it was some quiz game or something. LOL

Or then there's the people that will spew off a critique, and after you read it, you're still wondering "Ok.. I already knew all that.. But did you like it????" 

Get that music out, sus49.  It is sounding GREAT!
